The content of the invention
The present invention is to provide a kind of monoblock type spheroidal graphite cast-iron differential casing semiaxis endoporus and spread out mill processing method, and it is mainly
Solve the processing unit (plant) present in prior art needs housing being fixed with special fixture when processing housing, then adopts again
Housing is processed with honing head, the machining accuracy of the semiaxis endoporus of such housing is not high, finishing ability is poor, it is impossible to correct
The technical problem of mistake circle that the good process in preceding road is produced, hole partially etc..
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
The monoblock type spheroidal graphite cast-iron differential casing semiaxis endoporus of the present invention spreads out mill processing method, it is characterised in that described method
Including：Monoblock type spheroidal graphite cast-iron differential casing is placed on honing machine, the honing plug on honing machine is inserted into monoblock type
In two semiaxis endoporus of spheroidal graphite cast-iron differential casing, enter after the skive bar spreading on honing plug with semiaxis endoporus
Row face is contacted, and honing plug carries out front-rear reciprocation movement, until skive bar goes out required roughness to semiaxis inner bore honing.
After honing plug is inserted into monoblock type spheroidal graphite cast-iron differential casing, skive bar can radial direction spreading, boart boart
Therefore wheel bar can carry out face with the semiaxis endoporus of monoblock type spheroidal graphite cast-iron differential casing and contact, and thus change traditional work
The honing method that part is fixed, honing head floats, so that monoblock type spheroidal graphite cast-iron differential casing has higher surface accuracy,
Surface roughness can reach Rz3.After honing plug is moved back and forth on honing machine, due to skive bar and semiaxis endoporus
With face contact, such semiaxis endoporus can be close to honing, and honing effect is relatively good.
Preferably, described honing machine includes workbench, workbench is provided with honing machine main tank, fuel tank, honing machine
Main tank is provided with honing plug, and the outer surface of honing plug is connected with skive bar, workbench also by expanding mechanism
Provided with the bearing support of monoblock type spheroidal graphite cast-iron differential casing, honing plug can be supported.Skive bar is covered in honing core
On the outer surface of rod, it can be adjusted according to the semiaxis diameter of bore of supporting monoblock type spheroidal graphite cast-iron differential casing, from
And adapt to various sizes of semiaxis endoporus.Bearing support can not only play a part of supporting, moreover it is possible to play and monoblock type spheroidal graphite is cast
The effect that iron differential casing is positioned.
Set preferably, described expanding mechanism includes in the spreading groove being radially distributed in honing plug, spreading groove
There are tensioner spring, tensioner spring external connection skive bar, skive bar is the multisection type of arc, and it is around cyclization
Shape.Tensioner spring can adjust the amplitude of skive bar spreading, it is ensured that skive bar can all the time be close to and hold entirety
The inner surface of the semiaxis endoporus of formula spheroidal graphite cast-iron differential casing.Skive bar can be a plurality of, and it ensure that honing
All inner surfaces of semiaxis endoporus.
Preferably, the outer surface of described skive bar is provided with some projections, projection is into diagonally distributing.By convex
Block can not only increase the abrasion resistance of skive bar, moreover it is possible to so that honing plug is when moving reciprocatingly, increase honing
Contact area.
Preferably, the outer surface of described honing plug is provided with fixed diamond emery wheel bar, fixed diamond emery wheel bar
Outer surface be provided with groove.Fixed diamond emery wheel bar can be arranged at intervals with retractable skive bar, such Buddha's warrior attendant
After the abrasion to a certain degree of stone sand wheel bar, fixed diamond emery wheel bar can continue to carry out honing to semiaxis endoporus so that the whole top gem of a girdle-pendant
The service life of grinding machine can be lengthened, and fixed diamond emery wheel bar can also play a part of positioning support semiaxis endoporus.
Groove can have certain angle the gap between movable skive bar, and such honing gets up more complete.
Therefore, the present invention by the skive bar of spreading with semiaxis endoporus progress face using can be contacted, such top gem of a girdle-pendant
Core grinding rod will not float, and can be close to semiaxis endoporus and carry out reciprocally honing, so ensure that the machining accuracy of semiaxis endoporus,
It is simple and reasonable for structure.
